Description
La présente invention concerne les balais d'essuie-glace pour véhicules automobiles, tels que ceux utilisés pour l'essuyage des pare-brises, des lunettes arrière ou des phares de véhicules. The present invention relates to windscreen wiper blades for motor vehicles, such as those used for wiping windshields, rear glasses or vehicle headlights.
Ces balais, qui sont montés de manière amovible à l'extrémité de bras oscillants, sont destinés en général à essuyer des surfaces présentant une certaine courbure et ils doivent donc pouvoir se déformer dans un plan orthogonal à la surface à essuyer. Pour permettre d'obtenir une telle déformation, les balais connus sont en général constitués par un support qui peut être monté de manière amovible sur un bras d'essuie-glace, ce support recevant des ponts pivotants et dont les extrémités comportent des griffes destinées au montage d'une raclette d'essuyage en caoutchouc. These brushes, which are removably mounted at the end of the swinging arms, are generally intended to wipe surfaces having a certain curvature and they must therefore be able to deform in a plane orthogonal to the surface to be wiped. To allow such a deformation to be obtained, the known brushes generally consist of a support which can be removably mounted on a wiper arm, this support receiving pivoting bridges and the ends of which have claws intended for the mounting of a rubber wiper blade.
Ces balais d'essuie-glace connus peuvent ainsi posséder une grande déformabilité qui peut être nuisible lorsque la courbure de la surface à essuyer varie beaucoup, la pression d'application étant fournie seulement au point d'articulation du balai sur le bras et risquant de provoquer des soulèvements. These known wiper blades can thus have a high deformability which can be harmful when the curvature of the surface to be wiped varies greatly, the application pressure being supplied only at the point of articulation of the blade on the arm and risking cause uprisings.
L'invention vise à obtenir, dans un balai d'essuie-glace du type précédent, des déformabilités pratiquement indépendantes de part et d'autre du point d'articulation sur le bras, ce qui élimine pratiquement tout risque de soulèvement comme il peut s'en produire avec les balais connus lorsqu'ils se rencontrent dans les zones de grande courbure. The invention aims to obtain, in a wiper blade of the above type, practically independent deformability on either side of the point of articulation on the arm, which virtually eliminates any risk of lifting as it may be. '' produce them with known brushes when they meet in areas of great curvature.
Ce but est atteint, conformément à l'invention, grâce à un balai d'essuie-glace pour véhicule automobile destiné à être monté de manière amovible à l'extrémité d'un bras d'essuie-glace et comportant un support muni de moyens de fixation audit bras ainsi qu'une raclette d'essuyage reliée audit support, caractérisé par le fait que le support est solidaire d'une pièce allongée déformable élastiquement et portant une portion de ladite raclette, ledit support comportant, à l'opposé de ladite pièce allongée par rapport au point de montage du bras, un point de pivotement pour un pont de support de la portion de la raclette non portée par ladite pièce allongée. This object is achieved, in accordance with the invention, thanks to a wiper blade for a motor vehicle intended to be removably mounted at the end of a wiper arm and comprising a support provided with means for fixing to said arm as well as a wiping squeegee connected to said support, characterized in that the support is integral with an elongated elastically deformable piece carrying a portion of said squeegee, said support comprising, opposite said elongated part with respect to the mounting point of the arm, a pivot point for a support bridge for the portion of the squeegee not carried by said elongated part.
On a représenté dans les dessins annexés, à titre d'exemple, un tel balai d'essuie-glace. Dans ces dessins: There is shown in the accompanying drawings, by way of example, such a wiper blade. In these drawings:
—■ la fig. 1 est une vue en élévation latérale, partiellement en coupe longitudinale, d'un balai selon une première forme de réalisation de l'invention; - ■ fig. 1 is a side elevational view, partially in longitudinal section, of a brush according to a first embodiment of the invention;
— la fig. 2 est une vue en coupe selon A-A de la fig. 1 ; - fig. 2 is a sectional view along A-A of FIG. 1;
— la fig. 3 est une vue en coupe selon B-B de la fig. 1 ; - fig. 3 is a sectional view along B-B of FIG. 1;
— la fig. 4 est une vue en élévation latérale, partiellement en coupe longitudinale, d'un balai selon une seconde forme de réalisation de l'invention; - fig. 4 is a side elevational view, partially in longitudinal section, of a brush according to a second embodiment of the invention;
— la fig. 5 est une vue en élévation latérale d'un balai selon une troisième forme de réalisation de l'invention; - fig. 5 is a side elevational view of a brush according to a third embodiment of the invention;
— la fig. 6 est une vue de dessus d'une partie du balai de la fig. 5, le support étant supposé transparent; - fig. 6 is a top view of part of the brush of FIG. 5, the support being assumed to be transparent;
— la fig. 7 est une vue en coupe selon C-C de la fig. 5 ; - fig. 7 is a sectional view along C-C of FIG. 5;
— la fig. 8 est une vue en coupe selon D-D de la fig. 5. - fig. 8 is a sectional view along D-D of FIG. 5.
Dans l'exemple de réalisation des fig. 1 à 3, le balai comprend un support 1 prolongé d'un côté par une pièce allongée 2 munie de griffes 3 de manière à enserrer sensiblement une moitié d'une raclette d'essuyage 4. A l'opposé de la pièce 2, le support 1 comporte un axe d'articulation 5 d'un pont 6. Dans l'exemple décrit, le pont 6 porte directement, par ses griffes d'extrémité 6', la seconde partie de la raclette 4. Bien entendu, si la longueur de la raclette le nécessite, le pont 6 peut porter à au moins une extrémité un petit pont pivotant dont les extrémités supportent la raclette. In the embodiment of FIGS. 1 to 3, the brush includes a support 1 extended on one side by an elongated part 2 provided with claws 3 so as to substantially enclose one half of a wiping squeegee 4. Unlike part 2, the support 1 comprises a hinge pin 5 of a bridge 6. In the example described, the bridge 6 carries directly, by its end claws 6 ', the second part of the squeegee 4. Of course, if the length of the squeegee requires it, the bridge 6 can carry at at least one end a small pivoting bridge whose ends support the squeegee.
La pièce allongée 2, qui est d'une seule pièce avec le support 1 dans l'exemple des fig. 1 à 3, est en matière élastiquement déformable, par exemple en polycarbonate, et comporte une certaine courbure à l'état de repos, ce qui assure une précontrainte lorsque la raclette est appuyée sur la surface à essuyer. C'est essentiellement cette précontrainte qui assure que la partie de raclette 4 serrée entre les griffes 3 épouse la courbure de la surface à essuyer. The elongated part 2, which is in one piece with the support 1 in the example of FIGS. 1 to 3, is made of elastically deformable material, for example polycarbonate, and has a certain curvature in the rest state, which provides prestressing when the squeegee is pressed on the surface to be wiped. It is essentially this prestressing which ensures that the squeegee part 4 clamped between the claws 3 follows the curvature of the surface to be wiped.
Le support 1, dans la zone de l'axe d'articulation 5, a une section en forme de U dans laquelle est logé le pont 6, lequel comporte deux bouts d'axe 8 qui viennent s'encliqueter dans deux trous 7 formés dans les ailes du U du support 1, ce qui permet un montage très simple et rapide. The support 1, in the area of the articulation axis 5, has a U-shaped section in which the bridge 6 is housed, which has two ends of axis 8 which snap into two holes 7 formed in the wings of the U of the support 1, which allows a very simple and fast assembly.
Le support 1 comporte un évidement 9 destiné à recevoir l'extrémité en forme de crochet 10 d'un bras d'essuie-glace. A cet effet, une paroi de l'évidement 9 comporte une surface cylindrique 11 contre laquelle peut pivoter l'arrondi du crochet 10. La paroi opposée de l'évidement 9 comporte une butée élastique 12 qui retient l'extrémité recourbée du crochet 10 après s'être déformée pour la laisser pénétrer en ménageant un certain jeu pour permettre une rotation limitée du support 1 par rapport au crochet 10. The support 1 comprises a recess 9 intended to receive the hook-shaped end 10 of a wiper arm. For this purpose, a wall of the recess 9 has a cylindrical surface 11 against which the rounding of the hook 10 can pivot. The opposite wall of the recess 9 has an elastic stop 12 which retains the curved end of the hook 10 after being deformed to allow it to penetrate while leaving a certain clearance to allow limited rotation of the support 1 relative to the hook 10.
La pression d'appui du bras-crochet 10 est transmise au point d'articulation 5 par l'intermédiaire du support 1, de sorte que le pont 6 peut s'incliner selon la courbure de la surface balayée par la seconde partie de la raclette 4, pratiquement sans influencer la forme de la pièce allongée 2. The support pressure of the hook arm 10 is transmitted to the articulation point 5 via the support 1, so that the bridge 6 can tilt according to the curvature of the surface swept by the second part of the squeegee 4, practically without influencing the shape of the elongated part 2.
La forme de réalisation de la fig. 4 est identique à la précédente, la seule différence résidant en ce que l'évidement 9 comporte un axe transversal 13 sur lequel vient s'encliqueter à pivotement une cage 14 dans laquelle vient se loger le crochet 10, un doigt élastique 15 venant emprisonner son extrémité. The embodiment of fig. 4 is identical to the previous one, the only difference being that the recess 9 has a transverse axis 13 on which a cage 14 is pivotally latched in which the hook 10 is housed, an elastic finger 15 trapping its end.
Dans la variante des fig. 5 à 8, le support 1 et la pièce allongée 2 sont séparés l'un de l'autre, le support 1 pouvant être métallique et la pièce 2 en matière plastique élastique. Le support 1 comporte une section en forme de U munie de deux tétons transversaux 16 (fig. 7) pénétrant dans des évidements correspondants 17 de la pièce 2, pour permettre le pivotement du support par rapport à la pièce 2. Ce pivotement est limité par la pénétration avec jeu de pattes repliées 18 du support 1 dans des rainures 19 de la pièce 2, le montage In the variant of fig. 5 to 8, the support 1 and the elongated part 2 are separated from each other, the support 1 possibly being metallic and the part 2 made of elastic plastic. The support 1 has a U-shaped section provided with two transverse studs 16 (fig. 7) penetrating into corresponding recesses 17 in the part 2, to allow the support to pivot relative to the part 2. This pivoting is limited by penetration with set of folded legs 18 of the support 1 into grooves 19 of the part 2, mounting
